Description

Shunt drain pipe

Technical Field

The utility model relates to the technical field of rainwater and sewage diversion drainage, in particular to a diversion drainage pipe.

Background

The rain and sewage split flow is a drainage system, which is a drainage mode of separating rainwater and sewage, conveying the rainwater and the sewage by one pipeline respectively and discharging or carrying out subsequent treatment. Rainwater is directly discharged to a river channel through a rainwater pipe network, or the household drainage device can be used for collecting rainwater and then secondarily utilizing the rainwater to water vegetables and the like, sewage is collected through a sewage pipe network and then is sent to a sewage treatment plant for treatment, and pollution caused by the fact that the sewage directly enters the river channel is avoided. The collection, utilization and centralized management of the rainwater can reduce the impact of the water quantity on the sewage treatment plant and ensure the treatment efficiency of the sewage treatment plant, but the rainwater can be mixed with garbage such as plastic bags and the like to directly enter the river and pollute the river, the common filtering equipment filters the garbage mostly through a filter screen, the garbage brought by the rainwater is mainly solid garbage, the filter screen is easy to be blocked, the normal running of pollution discharge is not facilitated,

At present, most of rainwater and sewage diversion mostly adopts two pipelines to collect rainwater and sewage respectively, no intersection exists in the whole process, rainwater and sewage can be well diverted, but when rainwater is collected, some sundries and the like are often mixed in the rainwater, the traditional rainwater collection pipeline cannot clean the rainwater, and the rainwater can be drained along with the rainwater; and when encountering great rainwater, the rainwater drainage pipeline can appear overload operation, and can not timely drain rainwater, or when encountering accidents at the rear end of the rainwater pipeline, and causing accidents such as unsmooth drainage or collapse, no emergency pipeline is used for drainage, and the maneuvering performance is poor.

For example, a double-layer drainage canal for diversion of rain and sewage, which is disclosed in patent publication No. CN 212534397U, is described as "comprising a drainage canal, a partition plate is detachably mounted in the drainage canal, a connecting groove matched with the partition plate is formed on the inner side wall of the drainage canal, a fixing device is arranged between the partition plate and the drainage canal, and a connecting device is arranged between two adjacent drainage canals. The double-layer drainage canal for diversion of rain and sewage consists of the drainage canal and the partition plate arranged in the drainage canal, has simple structure, convenient installation, lower manufacturing and using cost and better economic applicability, and is suitable for popularization and use. The rainwater and sewage drainage pipe can only respectively drain rainwater and sewage, but a large amount of impurities in the rainwater can not be filtered, and emergency treatment can not be performed when the rainwater is large or accidents such as blockage, maintenance, collapse and the like occur at the rear end of the rainwater drainage pipe.

In order to solve the problems, the utility model provides a diversion drain pipe which can divert rainwater and sewage, can carry out emergency drainage through a sewage pipeline when the rainwater is large and can not be discharged in time, and can filter a large amount of dirt impurities in the rainwater.

When the water surface height of rainwater in the drainage well is higher than the bottom of the strip-shaped drainage groove, floating matters on the water surface enter the drainage box along with the water flow, the transverse opening size of the strip-shaped drainage groove is smaller than that of the drainage box, namely the opening area of the strip-shaped drainage groove is smaller than that of the inner opening area of the drainage pipe, and the water flow at the upper part of the water surface can still enter the drainage box when the water surface height is higher than the middle part or the upper part of the strip-shaped drainage groove; flows into the sewage drain pipe. When suspended matters enter the drain pipe, the one-way valve is opened to the drain pipe, and the suspended matters enter the drain pipe along with water flow. The gear of the drain pipe is far smaller than the diameters of the drain pipe and the drain pipe.

The beneficial effects are that: the device can realize draining to the rainwater to carry out multistage filtration to the dirt impurity that mingles with in the rainwater, avoid impurity to block up the filter in great degree, be provided with V-arrangement communicating pipe and can not in time carry out the drainage emergency to the blow off pipe in too big drainage of rainwater water pressure, and avoid sewage in the blow off pipe to get into in the drain pipe, be provided with the drainage pipe and can arrange the suspended solid in the drainage well to the sewer pipe.
